Do you snack your way through it? Do you listen to music? Do you have break-down?
For me, I put up with it for as long as I could, but sometime my brain do this thing where it trick me to jump into bed and roll around for the satisfaction of "resting" but then I would pass out, and wake up with guilt. Another thing that come with it is the anxiety of having to come up with the plan B afterward; like what period of the day should I divide out the time to finnish the rest of the homework. Once in a while I though that I did a pretty amazing job at doing last minute stuff and that I'm spontaneous..but then it's not really that.
